| Is the diameter of Jupiter 142,800 km? | yes |
| What is Mercury's surface made of, what is the dominant element? | silicates, sulfure |
| Is Mercury's atmosphere thin because of solar radiation? | yes |
| Does Mercury have a large iron core, and what gives it its color? | yes, graphite |
| What is Venus' surface covered by? | hot layers of mantle |
| What is on Venus' young and volcanically active landscape? | volcanoes, rifts, mountains, valleys |
| What is the dominant rock type of Venus? | basalt |
| Is Venus' dense, toxic atmosphere made up of sulfuric acid which gives it its color? | yes |
| How is Venus similar to Earth? | size, mass, composition, and density |
| What are the dominant elements in the Earth's crust? | oxygen, silicon, aluminum, and orion |
| What are the 3 rock types? | igneous, metamorphic, sedimentary |
| Is the Earth's atmosphere made up of 78% nitrogen, 21% oxygen, and 0.9% argon? | yes |
| What is the only known planet which can support life, and with continental and oceanic crust? | Earth |
| What is Mars made of? | volcanic basalt rock |
| What makes Mars red? | iron oxide |
| What is the dominant gas in Mars' atmosphere? | carbon dioxide |
| Do any of the gas giants have solid surfaces? | no |
| What are the 2 dominant gases in gas giants? | hydrogen and helium |
| What makes Uranus and Neptune blue? | methane |
| Do terrestrial planets have a crust, mantle, and core? | yes |
| Do ice giants have a core, mantle, and atmosphere, but not a crust? | yes |
| Are terrestrial planets made up of rock, metal, silicate, iron, and nickel? | yes |
| Are gas giants made of hydrogen and helium, along with heavier elements? | yes |
| Are terrestrial planets denser than gas giants? | yes |
| Do terrestrial planets have thin atmosphere? | yes |
| Do gas giants have thick, unstable atmospheres? | yes |
| Gas giants are smaller than terrestrial planets. True or False? | false |
| Why is Venus the hottest planet? | Carbon dioxide in its atmosphere traps the Sun's heat, causing a "runaway greenhouse effect." |
| What are asteroids? | small, rocky objects that revolve around the sun. They are found in the asteroid belt between Mars and Jupiter. |
| What are comets? | cosmic snowballs, made of frozen gases, rock, and dust. They also orbit the Sun. |
| What are meteoroids? | space rocks made of silicon and oxygen, also iron and nickel. They come from asteroids or comets. When they become smaller, they turn into meteors. |
| What is the Kuiper Belt? | large, circular-shaped region of icy bodies. |
| Where do short-period comets originate? (as proposed) | The Kuiper Belt. |
| What is the Oort Cloud? | large, spherical shell which surrounds the Sun, planets, and objects found in the Kuiper Belt. It is filled with ammonia and methane ice. |
| Where do long-period comets originate? (as proposed) | The Oort Cloud. |
| What are dwarf planets? | round, celestial objects that orbit the Sun. |
| Are the classifications to be a dwarf planet are: orbits the Sun, has enough mass to be circular, has not cleared the neighborhood near its orbit, and is not a moon? | yes |
| Can Pluto clear its orbital path? | no |
| Are dwarf planets cold and smaller than the Sun, and what's its average temperature? | yes, -400 F |
| What planet has the most moons? | Saturn |
| Do gas giants have the most moons? | yes |
| What are the 2 planets without moons? | Mercury and Venus |
| How long does it take for sunlight to reach Earth? | 8 minutes |
| How many moons does Saturn have? | 146 |
| What planets have rings? | gas |
| What is a moon? | An object that orbits a planet or something else that is NOT a star. |
